R-和J-平凡正则语言的句法复杂性

Syntactic Complexity of R- and J-Trivial Regular Languages

Janusz Brzozowski, Baiyu Li

摘要:

正则语言的句法复杂度是它的句法半群的基数。正则语言类的子类的语法复杂度是该类中语言的最大语法复杂度,作为这些语言的状态复杂度n的函数。研究了R-平凡正则语言和J-平凡正则语言的句法复杂性,证明了n![e(n-1)!]分别是这些语言的严格上限。我们还证明了2^{n-1}是J-平凡正则语言的反转的状态复杂度的紧上界。

英文摘要:

The syntactic complexity of a regular language is the cardinality of its syntactic semigroup. The syntactic complexity of a subclass of the class of regular languages is the maximal syntactic complexity of languages in that class, taken as a function of the state complexity n of these languages. We study the syntactic complexity of R- and J-trivial regular languages, and prove that n! and floor of [e(n-1)!] are tight upper bounds for these languages, respectively. We also prove that 2^{n-1} is the tight upper bound on the state complexity of reversal of J-trivial regular languages.
